SPLIT COLLAR.

SPECIFICATION formingpart of Letters Patent No.'709,366, dated September16, 1902.

(No model.)

To all whom, it may concern:

Beit known thatI, ERNEST HENRY SEXTON, a citizen of the United States,and a resident of Sandyhill, in the county of Washington and State of.New York, have invented a new and Improved Split Collar, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a new and improved splitcollar which is simple and durable in construction and readily appliedto and securely locked in place on a shaft or other revolving part.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment ofthe invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a perspective view of the improvement. Fig. 2 is across-section of the same as applied with the parts in a lockedposition, and Fig. 3 is a like view of the same Withthe parts in anunlocked position.

The split collar consists, essentially, of the members A and B, havingsemicircular bores or recesses, the Walls of which securelyand irmlyengage the peripheral surface of the shaft C or other part on-which thecollar is to be fastened.` The members A and B are connected with eachother by a pivot D to allow of opening the collar and placing it inposition on the shaft without taking the latter out of its bearings, andon the free end of the member A is pivoted awlinkE, pivotally connectedwith a cam-lever F, formed on its fulcrum end with aGaIn-surface F',adapted tobe engaged by a lug B on the member B, so that when themembers A and Bare in posi-tion on the shaft C, as shown in Fig. 3, andthe lever F is swung into the closed position (shown in Fig. 2) then thecam-surface F presses against the lug B' to cause the link E to exert apull on the member A, whereby both members are drawn toward each otherand in iirm contact with the peripheral sur-- face of the shaft C tosecurely clamp the collar to the shaft. The link E can be lengthened orshortened to insure proper working of the cam-lever F, and for thispurpose the link has a threaded end E', screwingiu a ball E2, tting in asocket A on the outer face of the free end of the member A. A pin E3 isheld in lthe flanges A2 of the member A and engages the outer end of thehall E2 to hold the latter iu position in the socket and to allow theball to turn in any direction. Now when the link E and its cam-lever Fare in an open position the said link can be screwed in or out in theball E? to bring the cam-surface F in proper relation to the lug B toinsure secure clamping of the members on the shaft C. The members A andB are formed with the annular anges A2 B2 for forming a space for thelink E and lever E to rest in when the collar is clamped in place, sothat no portion of the link and lever projects beyond the peripheralfaces of the flanges, and hence form no projections liable to catchworkingmens aprons or other garments, thus rendering the collarperfectly safe for use on shafts extending close to floors, duc. When itis desired to remove the collar, the operator simply swings thecam-lever outward, with the link E as the fulcrum, to disengage thecam-surface F Vfrom the lugB (see Fig. 3) to allow partial opening ofthe members,`and then the lever, with the link E, is swung outward toallow the members to swing suiiiciently to disengage the shaft C. Thecam-surface F' has astraight portion, as shown in Fig. 2, to rest fiaton the flat top of the lug B at the timeA the lever F is in a closedposition, so that the lever is not liable to accidentally swing into anopen position when the shaft C, and with it the collar, is rotating.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. A split collar, comprising members hinged togetherone of the members being provided with `a recess in its periphery, alink pivotally connected with the free end of one of the members, and acam-lever fulcrumed on the free end of the link and adapted to engage asurface on the other member and to lie within the recess thereof, as setforth.

2. A split collar, comprising ilanged menibers hinged together, a linkpivotally connected with one member and adapted to ex- IOO tend betweenthe flanges of the members, and a cam-lever fulorumed on the link andadapted to engage a lug on the other member, the said lever when closedextending between the flanges of the member having the said lug', as setforth.

3. A split collar, comprising members hinged together, a link adapted tobe lengthened or shortened and having a balland-socket connection withthe free end of one of the said members, and a cam-lever fulcrnmed onthe free end of the said link and adapted to engage the free end of theother member, as set forth.

4. A split collar, comprising members hinged together, a ball mounted ina Socket in one member and havinga screw-threaded socket, a linkscrewing into the ball, and a cam-lever pivoted to the free end of thelink and'adapted to engage a lug on the other member, as set forth.

In witness whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ERNEST HENRY SEXTON.
